What is NFC?
NFC is a short-range wireless technology used to create a connection to share information between your device and other NFC-enabled devices or NFC tags. Features on your device that use NFC technology include Android™ Beam, Tap and Pay, and Tap and Go.
Depending on the apps you have installed on your device and the NFC compatibility of other devices, some of the ways you can use NFC include:
- Pass a picture to your friend.
- Tap an NFC tag to unlock your device using the Smart Lock feature.
- Grab a coupon from a poster you see on the street.
- Send a webpage you're viewing to a friend.
- Transfer your device data to a new device.
- Exchange contact cards with a new friend or business acquaintance.
- Tap an NFC-enabled printer to print a message from your device.
Some NFC apps are designed to simulate a physical card, such as a credit card, a public transit pass, or an access badge. Some of the ways you can use these types of NFC apps include:
- Pay for your morning coffee without taking out your wallet.
- Pay for your bus or subway ride.
- Gain access to your building when you get to work.
To use NFC, you simply tap the back of your device to the back of another NFC-enabled device or an NFC tag.
